Iboga Panacea

I have a bunch of 2 year old Iboga seeds and need to learn the best way to sprout them. Roach said there are ways of reviving them but never told me how in pm so I figured I would make it a bit more public to see if that gets attention. Please, any techniques or ideas would be greatly appreciated as these seeds have already been sent out to various parts of the world. I have been holding out on sending the rest out until I can learn of a proper or most proper technique.
